Why do divers exhale when surfacing?
As the diver ascends, the air in the lungs expands as surrounding water pressure decreases. Exhaling allows excess volume to escape from the lungs, and by exhaling at a suitable rate the diver can continue exhaling throughout the ascent and still have air in his or her lungs at the surface.
At what depth do you have to worry about the bends?
The Bends/DCS in very simple terms You do not need to understand much science to understand DCS how to avoid getting it. Anyone who dives deeper than 10 metres (30ft.) while breathing air from a scuba tank is affecting the balance of gases inside the tissues of their body. The deeper you dive, the greater the effect.

How do you cure the bends?
The optimal treatment is the use of a hyperbaric oxygen chamber, which is a high-pressure chamber in which the patient receives 100% oxygen. This treatment reverses the pressure changes that allowed gas bubbles to form in the blood stream.
Will the bends go away on its own?
In some cases, symptoms may remain mild or even go away by themselves. Often, however, they strengthen in severity until you must seek medical attention, and they may have longer-term repercussions.
How deep can you dive without decompression?
The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.
How can we prevent bends?
Ascend no faster than 30 feet per minute. Always perform a safety stop at 15 feet for three to five minutes. Remember, the ascent from safety stop to the boat is the most critical distance of your ascent, so go slow. Keep warm during and between dives.
